More to come from Arsenal - Wenger

Arsene Wenger has insisted there is 'more to come' from his Premier League leaders, despite their flying start to the season.

Tuesday's Champions League victory against Napoli was hailed as one of the finest Arsenal performances in many a year, but Wenger is keen to trample on rising expectations ahead of his side's trip to West Bromwich Albion on Sunday.

"I believe we can do better, there is more to come from us," stressed Wenger. "It depends now on how much we want it. How hungry we are to continue to improve.

"It is still very early, we have played just six games and there are still 32 games to go. Maybe [Manchester] United have not had the expected start, but Chelsea are not far and we have only played six games. Chelsea had a tough schedule they had United away, they had Tottenham and you have to put that into perspective.

"Of course it is important for us to maintain our consistent run. We have had quite a good consistent run since March."

Arsenal will register a Premier League club record ninth away win in succession if they are victorious at the Hawthorns, but Wenger is expecting a strong challenge from opponents who recorded an impressive 2-1 victory against Manchester United at Old Trafford last weekend.

"Basically we don't look too much [if a match] is it away or at home," Wenger added. "We play with the same desire and the same attitude and as well we have a level of confidence that is there.

"West Brom represents a good test for us because they are on the back of an outstanding result at Manchester United. Their confidence level is certainly high as well, so it is a very interesting test. They have a big squad and it's very difficult to predict who will play against us."

Wenger confirmed that defender Bacary Sagna will miss the next three weeks after sustaining a hamstring injury, with Carl Jenkinson set to deputise at in the vacant full-back berth.

"It is a blow because he is a very complete defender," added Wenger. "He is good in the air, can attack and he is a winner.

For us it's a handicap, but Jenkinson is growing as a player and I'm sure he will do very well."
